Sprint Speed Calculator
This calculator converts a sprint distance and time into speed in metres per second, kilometres per hour, and miles per hour. Enter your distance (in metres or yards) and the time taken in seconds. The formula is simply Speed = Distance / Time. Results are shown in all three common speed units with two decimal places. A benchmark table compares your speed against average untrained adults, trained recreational sprinters, and Usain Bolt's 100m world record (Berlin, 2009: 9.58 seconds average speed, 12.43 m/s peak). Benchmarks are sourced from World Athletics records and published exercise science research. Use this tool to track your 40-yard dash, 100m, flying 30m, or any other sprint effort.
Speed: -- m/s | -- km/h | -- mph
How sprint speed is calculated
Speed (m/s) = Distance (m) / Time (s)
Speed (km/h) = Speed (m/s) x 3.6
Speed (mph) = Speed (m/s) x 2.23694
Worked example
100 metres in 11.5 seconds:
- Speed = 100 / 11.5 = 8.70 m/s
- km/h = 8.70 x 3.6 = 31.30 km/h
- mph = 8.70 x 2.23694 = 19.46 mph
Converting yards to metres
1 yard = 0.9144 metres. The 40-yard dash (36.58 m) in 4.4 seconds = 8.31 m/s (29.93 km/h, 18.60 mph).
Sprint speed benchmarks
| Benchmark | m/s | km/h | mph | Notes |
|---|---|---|---|---|
| Average untrained adult | 6.00 | 21.60 | 13.40 | |
| Trained recreational sprinter | 9.00 | 32.40 | 20.10 | |
| Usain Bolt 100m WR (Berlin 2009) | 10.44 | 37.58 | 23.35 | average speed |
| Usain Bolt peak speed (Berlin 2009) | 12.43 | 44.72 | 27.78 | 60-80m split |
Bolt's average speed = 100m / 9.58s = 10.44 m/s. Peak speed measured at 60-80m split by World Athletics timing systems, Berlin 2009.
Common sprint distances and contexts
| Distance | Context | Good amateur time |
|---|---|---|
| 40 yards (36.58 m) | American football combine test | 4.8 to 5.2 seconds |
| 60 m | Indoor sprinting, school tests | 7.5 to 9.0 seconds |
| 100 m | Olympic sprint | 12 to 14 seconds |
| Flying 30 m | Peak speed measurement (rolling start) | 3.0 to 3.8 seconds |
| 200 m | Olympic sprint | 25 to 32 seconds |
Sprint speed calculator: frequently asked questions
How do you calculate sprint speed?
Sprint speed is calculated by dividing distance by time: Speed = Distance / Time. The result in metres per second (m/s) can be converted to km/h by multiplying by 3.6, or to mph by multiplying by 2.23694. For example, running 100 metres in 10 seconds gives a speed of 10 m/s, which equals 36 km/h or 22.4 mph.
How was Usain Bolt's top speed calculated?
Usain Bolt's peak speed during his 100m world record of 9.58 seconds (Berlin, 2009) was measured by World Athletics using high-speed camera systems and laser timing. His peak instantaneous speed was recorded at 12.43 m/s (44.72 km/h, 27.78 mph), achieved between the 60 and 80 metre marks. His average speed over the full 100m was 10.44 m/s (37.58 km/h). The world record is maintained by World Athletics at worldathletics.org.
What is the average human sprint speed?
Average sprint speed varies with age, sex, fitness, and running technique. For untrained adults, a maximum sprint effort typically reaches 6 to 7 m/s (21.6 to 25.2 km/h, 13.4 to 15.7 mph). Trained recreational athletes may reach 7 to 9 m/s. Competitive sprinters typically exceed 9 m/s. Elite sprinters at the world-class level reach 11 to 12 m/s.
What factors affect sprint speed?
Sprint speed is determined by stride length and stride frequency (cadence). Longer strides and higher cadence both increase speed. Biomechanical factors include leg length, ground contact time, force production, and ankle stiffness. Trainable factors include strength (particularly hip extensors and ankle plantar flexors), neuromuscular coordination, reaction time, and sprint-specific technique. Surfaces, footwear, wind, and altitude also affect recorded times.
How do I convert yards to metres for sprint timing?
One yard equals 0.9144 metres. To convert a sprint distance in yards to metres, multiply by 0.9144. For example, the 40-yard dash (a common American football combine test) is 40 x 0.9144 = 36.58 metres. A 40-yard dash time of 4.4 seconds therefore equals a speed of 36.58 / 4.4 = 8.31 m/s (29.93 km/h, 18.60 mph).
